Abstract [en]

In recent years an increasing number of organisations use process capability studies on a regular basis. Contemporaneous with the increasing number of organisations using process capability studies, warnings have been launched that imprudent use of numerical measures of capability, the so-called process capability indices, might lead the user to make erroneous decisions. As a result, many practitioners of today are left with a somewhat ambivalent attitude towards process capability studies. In order to reduce these ambiguities, this paper outlines the advantages and disadvantages of the method. The results presented are based on a survey performed among 97 Swedish organisations that use process capability studies on a regular basis
